Specification of Letters Patent.

Patented Oct. 26, 1909.

Application filed September 16, 1905. Serial No. 278,735.

To all whom it may concern;

Be it known that I, JOHN V. RICE, Jr., a citizenv of the United States,residing at Bordentown, in the county of Burlington and State of New'Jersey, have invented certain new and useful Improvements in Internal-Combustion Engines, of which the following is a specification. I

One object of the present invention is to improve the construction andmode of ,o'peration of the provisions which eflect the compressionnecessary for operating an internal combustion gas engine.

Another object of the invention is to effect the necessary compressionwithout having recourse to the crank case or to the cylinders in whichthe explosion occurs thereby obviating the well understood disadvantageswhich such ractice entails.

Another- 0 jeet of the invention is" ta provide for running an engine ofthe type recited on a comparatively low ade gas and f compression meansother than such as are self-contained in the engine.

Another object of the invention is to provide a self-starting multiplecylinder engine operate properly without a fly: wheel or at any ratewith a relatively small one.

Another object of the invention is to proengine in which the foreffecting compres-' unobjectionable, simple employed for that purcrankcase is not use and novel means are pose; and-other objects of theinvention will appear from the following description.

To these and other ends herelnafter set forth the invention comprisesthe im rove- 'inders shown in Fig; 1, illustrating ments to bepresently-described; and. ally The nature, characteristic features andscope of my invention will'be"more fully understood from the followingdescription taken in connection with the accompanying drawings forming;-part hereof-; and gin Figure 1, isa view inf" vertical section--illustrating portions ofv aj multipleggglind'en internal combustion enin'e em ying features of the invention. ig, 2, isa' rear'elevatienalview of the cyl; the ports thereof; Fig. 3, is a side elevatlonal'viewofthe engine shown Fig. 1, and Fig. 4,-is.

means-Bot exit for the pro tion', all'of which are too well understoodto a View single embodying features of the invention and ar- I rangedfor operation in drill or the like.

In the-drawings I have shown cylinders each having at its extreme endsexplosion chambers l and 2, arranged in alinement and havingintermediate of its ends an enlarged compression chamber 3. Goodpractice and machine design dictate that the chambers 1, 2 and 3, shouldbe internally cylindrical and I that the cylindrical chamber 3, shouldbe arranged eccentrica-lly in respect to the chambers l and 2, and sucha construction is therefore chosen for the purposes of. illustration,but the invention is of course not intended to be limited to thisparticular embodiment. Arranged for cooperation with the describedcylinder is a piston having its ends 4 and 5, properly fitted to tlieexplosion chambers 1 and 2, and having an enlarged offsetintermediate-portion 6, properly fitted to the compression chamber 3,which conconnection with a center of gravity of the engine. The endsshown as rovided with packing as externa ly cylindrical so as to suitthem for cooperation with the parts 1,2 and 3. Furthermore the portion6, is shown as dis.- posed eccentrically with respectto the parts 4and-5.

Referring to Figs. 1 and 2, 7, is a pistonv rod applied to theintermediate portion of thepiston and working through the compressionchamber 3,1so that its stufiing box orgland 8, is not exposed toan unduedegree of heat and is thereforedurable and easily kept tight. The pistonrod 7, reciprocates 'a cross-head 9, and the cross-head is connectedwith a" link rotary motion is imthrough the intervenrings and tion of a.drank 13.

in suitable ways 10, I

As illustrated, the cyl- 19 inders comprise sections of castingssuitably secured together and they may be provided with spaces as shownwhich constitute water es and affording 106 18, secured tothe cylindersof the pression chamber 3, of one cylinder with the I ex' losionchambers l and 2, of the adjacent cy inder. The charge is of courseintroduced into the. compression chambers as at 19, and 20, representsexhaust provisions.

In Fig. 4, the piston rod is arranged in the compression. chamber and isshown as made in two parts 21 and 22, of which the part 21, is securedto the piston and the part 22', isarranged ,to carrya drill-or the like.23-and 24, are the ports "which may be variously and appropriatelyarranged.

V It will be obvious to those skilled in the art to which my inventionappertains that modifications may be made in detail without departingfrom the spirit thereof, hence the invention is not limited further thanthe state of the art may require, but

Having thus described the nature and Ob-v jects of my invention, what Iclaim as new and desireto secure by Letters Patent is:

1. In. an internal combustion engine, the combination with a cylinderhaving an eccentric compression chamber between its ends, and a pistonin said cylinder-having an intermediate eccentric portion fitted to saidcompression chamber.

' 2; The combination in an internal combustionengine, of a pair ofcylinders arranged side by side, having closed ends forming explosionchambers, and eachrhavs ving, intermediate between its ends, an enlargedcompresslon chamber, pistons working in the said cylinders andhaving-their ends fitted to the said explosion chambers, and eachhavingalso an intermediate portion fitted to a compression chamber, andfluid conduits between the said compression chambers and the explosionchambers, a conduit leading from one end of each compression chamber toan explosion chamber of the other cylinder.

, 3.
